A schematic diagram of direct and indirect retwitters. After the publication of an original tweet from the author, direct followers 1 and 2 will immediately receive the message. Suppose 1 reposts the message, he becomes a direct retwitter. As a consequence, on the one hand, he will be the mediator for his follower 3, a possible indirect retwitter. On the other hand, because of the existence of the direct link from 2 to 1, the retweeting behaviour of retwitter 1 increases the number follower 2 receives the message.
